Understand white light colors and the phenomenon of color absorption & reflection. Learn what determines the color of light and how we can make the...
theory of light absorption, which takes into account in particular the multiple scattering of photons in an optically thick medium; the scattering is accompanied by a change in the photons’ frequency and, ultimately, by absorption of the photons by the particles of the medium. For sufficiently ...
The importance of the incorporation of such corrections, with the proper value for the internal reflection coefficient, is clearly demonstrated for both reflectance and transmittance theories. The limitation of transmittance theory to materials with a scattering power (SX) of greater than 0.5 is also ...
The reflection through the sample alters the polarization, and the degree of alteration provides thickness data to 0.1-nm precision. These instruments have wide applicability in the semiconductor industry and as tools for the measurement of organic films of monolayer dimensions....
In that case, the wave is only partially absorbed, and as a result, it transfers lower energy levels through the material. This is called partial absorption. Absorption occurs in waves when they do not reflect or transmit. The diagram models wave reflection and wave transmission, which help ...

Normal black feathers reflected light in a manner consistent with classical glossy surface reflection theory21: the majority of energy was reflected in directions roughly equal and opposite to that of the directional incident light (Fig. 5a and Supplementary Fig. 9a, b). Thus, the darkest viewing...
The reflection approximation is illustrated on Fig. 7.4 for free←bound transitions into three repulsive states of OH: 12Σ−, 12Σ, and B2Σ+. The σ(E) curves exhibit the expected increase in width (and decrease in maximum intensity) as the negative slope of V′(R) at R′′e ...
(1) The incident electromagnetic wave can fully enter the interior of the material without reflection on the surface. That is, the matching characteristics of the material; (2) The electromagnetic wave entering the material can be quickly attenuated. To explore the microwave absorption performance, ...
